But yeah, I agree, the fact that 4.4 is fine kinda doesn't fit with the uncorrectable error theory. > Yes, that would be in the logs. Presumably.

At least I'm not aware of any other report of the same issue. My system with a F10h, rev E is just fine. > Do you want me to memtest for 24 hours? Yeah, that memtest crap never triggers any ECCs.
